On June 5, Zhou Yu came to a construction site in Daxing District, Yanjing, and the plant under construction was the graphene chip factory of Xinghuo Technology.

The 12-story building, which has been completed next to it and looks gray and has a somewhat simple appearance, is the R&D center laboratory.

These factories are assembled using prefabricated modules, and the construction speed is very fast, and the exterior wall of the R&D center is sprayed with a layer of protective paint on the surface of cement.

Yuan Keqing led Zhou Yu to visit the construction site, and at the same time invited merit and said: "Mr. Zhou, you see if my suggestion is very good, directly using prefabricated modules to build a house, can save 90% of the time."

The exterior of the house can be spray-painted, and the interior can be wallpapered, and people can go in and work without any health effects.

This is a laboratory, not a house where you live, so you don't need to decorate it. ”

"You've always had the right idea, and I'm happy with the speed of construction here.

I saw that most of the houses in the chip factory had been sealed, and in a week or so, they should all be completed. Zhou Yu said with satisfaction.

"As long as there is enough money in Huaxia, these construction companies can build it for you with quality and quantity, and if it is an ordinary prefabricated module plant, it can be built long ago.

Our chip factory has high requirements, it needs to be built into a dust-free workshop, and some workshops need to be built into a vacuum workshop.

This necessitates the use of state-of-the-art prefabricated modules, some of which need to be customized. Yuan Keqing explained.

"The holographic bracelet and virtual idol Xianghua continue to provide cash flow for our company, the company is not short of funds, and the chip factory must be completed with quality and quantity.

In particular, the anti-vibration level should be high, and the absolute stability of the equipment should be ensured, even if it is a low-level earthquake, people do not feel much, but the processing equipment will be displaced.

If the chip is processed off by even one nanometer, the entire wafer will be scrapped. Zhou Yu solemnly explained.

"Please rest assured that Mr. Zhou, as the supervisor, understands the quality of the chip factory, this requirement has been written into the contract, it is highly earthquake-proof, and earthquakes below level 6 will not affect chip processing." Yuan Keqing introduced with a smile.

"The chip factory has not yet been built, so let's go to the R&D center to have a look, and they are responsible for developing chip processing equipment.

Academician Tian Kai designed and completed the graphene chip and explored the process of graphene chip preparation.

The lab is also able to produce finished chips, and now he is working on the chip instruction set.

The real industrial production of chips depends entirely on whether the R&D center can manufacture qualified processing equipment. Zhou Yu said expectantly.

He and Yuan Keqing walked into the R&D center, where there are thousands of people serving the scientific research of Xinghuo Technology.

When Ma Shangshu saw Zhou Yu coming, he immediately came to greet him.

"Mr. Zhou, welcome to inspect the R&D center, we now have hundreds of scientific research projects and more than 80 laboratories here.

Research projects range from basic science to future scientific exploration. Ma Shangshu proudly introduced.

"Don't fix these useless, what am I going to do, can you count in your heart, where is the development of graphene chip processing equipment now.

Academician Tian Kai has figured out the theory and explored the three main processes of graphene wafer processing. Zhou Yu immediately asked.

Ma Shangshu wiped the fine sweat on his forehead, and said with some hesitation: "This, Mr. Zhou, the reactor for refining graphene wafers has been successfully developed.

We received data from the institute and optimized the reactor we were studying.

Now the production parameters have been formed, and they have been handed over to Xinghuo Precision Manufacturing Company to produce reactors and packaging equipment for graphene wafers, and we have also made a breakthrough, which is better than the 25% yield rate of the research institute, and the yield rate of our equipment processing chips has reached 85%. ”

"Don't avoid the important and light, these devices can be studied by relying on those people in the research institute, and it is not normal for these people in the R&D center to study them.

The core equipment for graphene chip manufacturing is the etching machine, which needs to etch graphene wafers with a 0.1 nanometer hydrogen atomic beam to divide one square meter of graphene wafers into standard chips.

Splitting graphene wafers into units with different effects through hydrogen atom beams is also the process of graphene chip encoding, and what is the progress of its research. Zhou Yu asked directly.

"This, this, the processing difficulty of the etching machine is too high, and we are now investing huge manpower and material resources to overcome the difficulties." Ma Shangshu said tangledly.

"Take me to the laboratory where the etching machine was developed to see, what difficulties did you encounter to get stuck for so long?

Academician Tian Kai told me that he chose the etching scheme because the domestic etching technology is relatively advanced and will not be stuck. Zhou Yu asked puzzled.

Academician Tian Kai's research institute has insufficient scientific researchers and technical reserves to complete the etching machine.

He thought that the research center could make a breakthrough here, but he didn't expect that they would also be stumped by this technology.

At that time, Zhou Yu chose to let the research institute and the research center go hand in hand to develop graphene chip processing equipment, and this method of wasting manpower and material resources was to prevent a unit from being stumped by a certain difficulty.

Unexpectedly, both the research institute and the R&D center were stumped by etching technology.

The group arrived at a large laboratory, where a group of researchers in white coats were pointing at a machine about two meters tall and 1.5 meters long and wide.

Zhou Yu saw that Yu Zhenfeng was also in the crowd, so he waved his hand to Yu Zhenfeng and beckoned him over.

"Director Yu, your R&D center is stumped by etching technology."

When Yu Zhenfeng heard Zhou Yu's question, he immediately explained: "Mr. Zhou, I have been communicating with Academician Tian Kai's research institute, and the problems we encountered are very similar.

This is not a problem of the principle of etching technology, but a problem that arises in real processing.

Academician Tian Kai designed a plan for processing graphene chips in accordance with the most advanced etching technology in China.

Academician Tian Kai does not understand the mechanical principle, he designed this standard, in theory the etching machine can process chips, but it is difficult to control it in the actual processing process.

Because in order to process a standard graphene transistor into a pattern that meets the requirements, it is necessary to adjust the duration and bombardment force of the hydrogen atom beam.

In the laboratory, several different hydrogen beam launchers can be made, each of which processes only one type of transistor.

The etching machine can not use this way, once this method is adopted, it is like engraving printing, each etching machine can only process one kind of chip, a transistor change, etching machine worth hundreds of millions of yuan will be completely abolished.

Even the richest enterprise cannot build such a luxurious production line. ”

When Zhou Yu heard Yu Zhenfeng's explanation, he immediately understood and said with a smile: "You just want to change engraving printing to movable type printing, but you can't break through the technical difficulties."

Yu Zhenfeng said with a wry smile: "Mr. Zhou, it means this, but the difficulty is completely different, not to mention other processing difficulties, that is, hydrogen atom beams with different attributes interfere with each other, and the high-frequency changes of hydrogen atom beams, these two problems cannot be solved."

Zhou Yu pondered for a moment, his eyes lit up, and said, "I have an idea, you can design multiple emission sources and prepare hydrogen atom beams with different properties.

The hydrogen beam launcher is like movable type printing and can be connected to multiple emission sources.

Connecting the launchers of each source, working at the same time, and then switching to different launchers immediately will not solve the problem you encounter. ”

Yu Zhenfeng was pleasantly surprised: "Mr. Zhou, this solution is very ingenious, so that the etching machine only needs to be larger, and the cost is acceptable."
